PFA (Perfluoroalkoxy)

PFA (PerFluoroAlkoxy) is similar to FEP (Polyfluoroethylenepropylene) in that PFA is a type of fluoropolymer that is similar to PTFE. PTFE has a higher temperature range but FEP/PFA has better mechanical properties than PTFE. FEP is considered to be more of a premium resin when working in extremely hostile environments where extended service requires resistance to thermal and mechanical stress. Offering more than 10 x the flex life of FEP, PFA will offer greater stability at high temperatures while reducing stress related breakdown and maintaining a low coefficient of friction.
